Hi. I want to ask a few questions that I didn't find answers to. 

1. The script will support redis cache? 

2. I have not found in the settings of the site map, is it? 

3. RocketChat today is the best free chat app. How deeply is rocketchat integrated with the social network? I would like to read the documentation or a detailed description of the integration application. 

4. The script fully supports mariadb server? 

5. When you download the images optimized? Thanks:)
